DEVICE FOR COLORING DRAWINGS.

I SPECIFICATION forming part of Letters Patent No. 686,462, dated memes12, 1901. Application filed May 4, 1898. Renewed April 28, 1900- SerialNo. 14,758. (No model.)

To all whom it may concern.-

Be it known that I, CARL W. A. KOELKE- BECK, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered a certain new and usefulImprovement in Coloring Devices for Drawings, of which improvement thefollowing is a specification.

The object of my invention is to provide means for coloring drawings;and to this end it consists of a new and improved coloring device and innew and improved apparatus for applying a coloring substance to thedrawings, all as hereinafter fully set forth.

My invention is particularly designed to be employed forcoloring certainparts of mechanical drawings-as, for example, sectional views-therebydoing away with the almost universal laborious practice of hatching. Itmay also be advantageously used to color any other part of a drawing.

To produce the results aimed to be accomplished, I preferably employ acoloring preparation, as crayon, which should be adapted to be mountedon a rotatable shaft in some convenient manner so that the crayon may bereadily brought in contact with that part or parts of the drawings to becolored and rotated at the desired velocity.

In the accompanying drawings, which illustrate an application of myinvention, Figure 1 is a plan view of a coloring device; Fig. 2, asectional view on line so a: of Fig. 1; Fig. 3, a central verticalsectional view showing the coloring device applied to a shaft; Fig. 4,an end view; Fig. 5, a plan view of an apparatus and coloring deviceapplied thereto constructed in accordance with my invention, and Fig. 6a side elevational view.

As shown by the drawings, the disk-shaped coloring device 1, which maybe of any preferred size and color and preferably a block or piece ofcrayon, is provided with a central aperture 2. I find that for coloringthe different parts of the usual mechanical drawings on almost any kindof drawing-paper and tracing-cloth the coloring device best suited forthis work is a piece or several pieces of crayon; but I do not desire tolimit myself to the use of crayon only as the coloring material.

The apparatus shown for usein connection with the coloring devicecomprises a rotatable shaft 3, journaled in suitable bearings on acasting 4:, which latter is fastened to and supported by a table 5. Oneend of the shaft '3 is screw-threaded and adapted to receive aninternally-screw-threaded chuck 6, on which the coloring device 1 ismounted and which is securely held in .place thereon between Washers 7,preferably made of rubber or of a similar material. In place of washersthe coloring device may be held between any suit able yielding parts.The chuck 6'for a portion of its length is externally screw-threaded toreceive the clamping-nut 8.

The shaft 3 is driven by means of the foottreadle' 9 and theintermediate mechanism comprising the Wheel 10, the connecting-rod 11,-the belt 12, and the small wheel 13 on the end of the shaft 3. Whilethis construction is simple and convenient, any other suitableconstruction may be employed for driving the shaft. 7

The table 5 is provided with grooves or tracks adapted to receive andguide the small loose wheels or rollers 14, on which the carriage 15rests and on which it is moved. To illustrate the manner of coloring thesheet of drawings, I have shown a sheet 16 on the carriage 15, showingcontact between the crayon 1 and the sheet. The disk-shaped crayon maybe vertically adjusted to the desired position by actuating thehand-wheel 17.

It may-sometimes be desirable to use more than one coloring-disk, and ifthis is the case two or more disks may be placed upon the shaft withoutmaterially altering the construction above described.

The crayon or other coloring device may be 0 conveniently brought intocontact with that part or parts of the drawing to be colored, and whenin that position it is rotated by the means shown and the coloringsubstance quickly and accurately applied to the draw- 5 ings.

The apparatus shown in connection with the coloring-disk may bedifferently constructed-that is to say, the shaft 3, having the disk ordisks mounted thereon, could be rotated by mo means of a crank, andother changes may be made that would come within the scope of myinvention, the characteristic features of which are a disk-shapedcoloring device adapted to be mounted on a rotatable shaft and means forrotating the coloring device,whereby a part or parts of adrawing maybecolored.

In the drawings I have shown a simple and convenient arrangement foraccomplishing the purpose for which my invention is designed. In thisconstruction the sheet of drawings placed on the carriage may be readilymoved under the coloring device, which latter may be vertically adjustedto the desired position.

By means of my invention a great saving of time and labor in thepreparation of drawings is possible.

I claim as my invention and desire to secure by Letters Patent-- 1.Means for coloring drawings, comprising, a color-disk of crayon or othersuitable coloring material, a rotatable shaft, the coloring-disk mountedon the shaft, and means for rotating the shaft and the color-disk,substantially as set forth.

2. Means for coloring drawings, compriscolor-disk, a movable surface onwhich the drawings to be colored are placed, and means for adjusting thecolor-disk with reference to the drawings, substantially as set forth.

In testimony whereof I have hereunto set 40 my hand.
